To all whom it may concern.

Be it known that I, CHARLES \V. TURNER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oxyhydrocarbon- Burners, of which the following is a specification.

This invention relatesto apparatus for generating and burning oxyhydrocarbon vapor or gas, containing oxygen, hydrogen and carbon, from a mixture of water and hydrocarbon oil, for heating steam-boilers, metallurgic furnaces, gas generators, domestic furnaces and other devices where a high heat is required.

The object of my invention is to provide, more particularly, for burning petroleum or other heavy hydrocarbon oil, by causing decomposition thereof in combination with water and recomposition of the elements to form oxyhydrocarbon gas under high heat and pressure-the gas being of high calorific value.

One of the special obj ects is to provide for separating, depositing and discharging earthy matter, asphaltum and other dense carbonaceous matter from the oil or vapor during the generating and burnin operation, so that no part of the generating coils or burners shall become clogged or obstructed, and so thata continuous strong flame and perfect combustion may be produced.

This invention is an improvement on the oxyhydrocarbon burner forming the subject of Letters Patent No. 7 46,409 granted to me December 8, 1903. The apparatus described in this patent has been in successful operation for a number of years, using kerosene or a similar distillate hydrocarbon oil, but I have found that it was not adapted for using petroleum or other heavy hydrocarbon by reason of the formation of deposits of asphaltum or other dense carbonaceous matter in the interior of the coils, thus obstructing them and stopping the generation and fiow of gas or vapor to the burners. In order to overcome this difliculty I provide and connect with the sections of coils, at a number of points, separating drums of larger diameter than the coils and having deposit pockets in which the dense carbonaceous matter is deposited, and from which it may be drawn or blown OK as required for keep ing the coils, pipes and burners free from obstructions.

While my burner apparatus is designed and adapted for effectively utilizing petroleum and other cheap heavy oil for combustlon, it can be used with equally economical results in burning kerosene or other intermediate oils.

The matter constituting my invention will be defined in the claims.

I'will now describe the details of construction of my oil burning apparatus byreference to the accompanying drawings, in which- Figure 1 represents a side elevation with parts in vertical section, and with parts of the generator diagrammatically arranged for more clearly showing the separating drums. Fig. 2 represents an elevation of the vaporizing and generating coils and the separatmg drums compactly arranged in proper pelation one to another for effective opera-- ion; 1

The vaporizing and generating coils 1 of my oxyhydrocarbon-burner apparatus are located in the fire-box of a steam boiler 2 or other furnace-where a high heat is required. The coils are divided into sect-ions, between which are interposed separating and depositing drums, one drum between each pair of coil-sections and a drum between the last coil-section and the burners, as will be described in detail below.

The oil supply tank 3 and water supply tank 4 will be mounted on a suitable support at any convenient distance from the generator and burner apparatus and are shown connected at their lower ends with a waterforce pump 5, the discharge pipe 6, having a valve 7, connecting with tank 4, and a branch'pipe 8, having a valve 9, connecting with tank 3. This water force pump is one of a number of devices which may be used for forcing water and oilfunder pressure into the vaporizing and gasifying coils. The liquid may be forced by air admitted under pressure at the tops of the tanks, in a well-known manner. I Before admitting water into tank 3, valve 9 being closed, the tank is filled with petroleum or other heavy hydrocarbon oil, and then when it is desired to force oil into the generating coils, the valve 9 will be opened, admitting water un der pressure below the body of oil. The oil feed pipe 10 connects with the top cftankqtj,

and with the middle portion of the heating and separating drum 15 located within the coils 23 and 26. Pipe 10 is provided with stop valves 11 and 13, an intermediate checkvalve 12 and a test cock 1 L. An oil vapor pipe 16 leads from the top of drum 15 to a T-iitting 16, with which a steam pipe 22 also connects, at the inlet of the mixing coil 23. lVith the top of water tank 4 connects a feed-pipe 17 leading to the base of the water heating or steam generating drum 18, fromthe top of which leads a pipe 22 to the T-fitting '16. The feedpipe 17 is provided with stop-valves 20 and 20 an intermediate check valve 19 and a test cook 21.

In order to determine the rate of flow and quantity of oil supplied through feed pipe 10, the valve 13 is closed, the test cock i l fully opened, and the valve 11 party opened and adjusted, so that the desired flow will be discharged through the test cock. This having been ascertained by ob servation, the test cock 14 is closed and valve 13 opened, leaving valve 11 at the proper adjustment for feeding the desired quantity or proportion of oil into the heating and separating drum 15. The flow of wa ter through pipe 17 will be controlledand the proportion determined by means of test cook 21 and adjustment of valve 20 in the manner above described with reference to the oil feed pipe.

I have found that satisfactory results may be obtained by dividing the coil of pipe, in

' which oxyhydrocarbon gas is generated,

into four sections or sets, as 23, 26, 29 and 32, and connecting the outlet of one coil section and the inlet of a succeeding coil section with an interposed separating and depositing drum for collecting and discharging asphaltum or other dense carbonaceous matter. The mixing coil 23, in which. steam and oil vapor are mixed, connects at its inlet end with T-fitting 16 and at its outlet end with the middle portion of a separating and depositing drum 24. An outlet pipe 25 leads from the top of drum 24 to the inlet end'ot coil section 26, fro'm the lower end of which an outlet pipe connects withthe middle portion of a separating and depositing drum 2?. The coil section 26 is called the combining and superheating coil. An outlet pipe 28 leads from the top of drum 27 to the inlet end of thedecomposing coil-section 29. The. outlet end of this coil con nects with the middle portion of a separating and depositing drum 30, from the top of which a pipe leads to the inlet end of the decomposing and recomposing coil sec-,

tion 32. The outlet end of this coil connects with the middle portion of the separating and depositing drum 33, from the top of which extends the outlet gas pipe 3%, which connects at its lower end with the horizontal gas pipe 35 connecting at both ends with the burners 36. Auxiliary smaller burners 37, 37, are connected with the gas pipe 35 and placed adjacent to the main burner 36. This provision is made so that if either one of the main burners becomes accident-ally extinguished, as sometimes happens, it will be re-lighted by one of the auxiliary burners.

Each of the separating and depositing drums 15, 24', 27, 30 and 33 is provided with a pocket 38 at its lower end, for receiving asphaltum, tarry matter and other dense carbonaceous matter. The burners 36 are also provided with depositing pockets below the inlet gas pipes 35. With the bottom of each pocket is connected a discharge-or blow-oil pipe 10, each. having a valve 42, and each connecting with a drain pipe 43 leading to a receiving tank 44. lVhenever it appears from the condition of the flame at the burners that any pipe or drum is becoming obstructed, any one or more of the valves 12 may be opened, permitting the heavy residuum or carbonaceous matter to be blown out and discharged into the receiving tank.

The coils may be maintained at a temperature between 800 F. and 1500 F,, and the oil and water may be forced into their respective drums at a pressure between fifty and seventy pounds, and in the proportion of three parts of oil to one of water, or four parts of oil to one of water: The proportions, however, of oil and water may be varied within wide limit, according to the character of heat required and to the quality of oil used.

\Vith a comparatively high heat and slow feed of oil to the drum 15, most of the lighteroils will be vaporized therein and the vapor passed over into themixi'ng coil 23, but if the temperature falls or the feed of oil is relatively increased, part of the lighter heated oil may flow over into the mixing coil 23, or to the T-fitting 16, where the current of steam would atomize it. In either case the earthy and tarry matter will be first separated from the oil and deposited in the pocket at the lower end of drum 15. Vaporization of the oil will be completed in coil 23. v

In putting the apparatus in operation, the oil and water tanks are first filled, the pump put into operation, and the relative flow of the oil and water through each food pipe adjusted as above-described. Some kind of oily waste may be first burned in the fire box below. the coils for heating them to a suificient temperature to vaporize oil"; A small flow of oil is then first admitted into drum 15, where it is vaporized and the vapor forced through all of the coil sections to the burners. After the heat is sufiiciently flowof oil will be gradually-increased until strong flames are produced at the burners,

and until the coil sections 29 and are heated to approximately 1000 F. The full supply of oil and water may now be fed coil section :26, where the vapors will be combined and superheated nearly to the point of decomposition. The combined vapors'will pass from drum 27 into coil section 29, where decomposition is partially efl'ected, and the resulting gaseous products will be discharged into drum 30 and passed therefrom into the coil section 32, where decorir position and re-composition are completed,

directly to the tanks.

resulting in the production of oxyh ydrocarbon gas, which after passing through drum 33 is supplied to the burner 36. In the coil sections 29 and 32, part of the oxygen Ofaiilfi steam combines with part of the carbon .ofathe oil to form carbon monoxid, while the hydrogen of the water is set free. The combined gases containing oxygen, by drogen and carbon, in a highly heated state, give a very high flame temperature at the burner. Thus highly economical results are produced in the combustion of petroleum or other cheap, heavy hydrocarbon oils.

The pressure in-the oil and water tanks will be registered by gages m and y applied to the outletpipes 10 and 17, as shown. 0''
